What s the deal with painting the wall with lime water and falling down?

Knowledge of painting walls.

1. The wall is generally divided into two situations, one is the wall that has never been painted, and the other is the wall that has been painted. The treatment of two different wall surfaces when painting is also different. Generally, new wall painting only needs to do an alkaline and moisture content test.

2. But if it is a wall that has been painted, you need to deal with some stains on the wall first. For dirty areas, wipe with a sponge or rag first, but be aware that if water is used during the cleaning process, you need to wait for the wall to dry completely before painting.

3. For the parts of the wall that are more damaged, such as cracks, etc., the wall needs to be repaired before painting. But if the wall is originally well preserved, then you can paint the wall directly, and you don't need so much preparation.

4. Remove the original old wall, which can ensure that the wall painting effect is better. Putty is also difficult to follow. After the old wall is removed, you can then use putty or scraping powder to level the wall to make the wall smoother.

5. After the wall is leveled, the next step is to polish, mainly to polish the uneven places on the wall with sandpaper to smooth and smooth. After the above steps are completed, you can enter the step of painting the wall. Generally, the paint is divided into two parts, first the primer, then the topcoat, the general principle is "one bottom and two sides", that is, one primer and two topcoats.

Brush the wall with lime water to fall down, because your lime water concentration is too high and low, and your lime water is too thin, so it is easy to flow down like water when brushing.

1. Drop the wall skin in a small area: The area is relatively small, and a little bit of a wall can be covered with a hanging painting, of course, this is only a temporary solution. 2. From the perspective of dealing with patching.

Fall off the loose part of the surrounding area and dispose of it at the same time. Brush the same latex paint down and you're good to go. 3. There is also a way to even the putty to fall off:

Deal with the base layer (that is, the part of the wall that falls off), and also split the putty first. After drying, lightly sanded with sandpaper. Then repaint the same paint (the best left when decorating).

The main reason for the white ash falling on the wall is that the putty is too thick. The base layer of the original wall was not cleaned. Or the first putty is not completely dry before proceeding to the next process.

After the acceptance of the project, there will generally be no problems. Only after a long period of time will it be time for the cracks to leak.

How to deal with the lime falling off the wall: scrape off the lime layer of the inner wall to scrape off the lime layer on the sedan wall, clean up the cement mortar layer painted outside the bricks, and then paint the waterproof material on the cement mortar layer. Demolition.

If the local spalling is serious, the original wall will be removed to the wall base, repainted with an interface agent or sealing primer, and then leveled according to the plaster, pasted with mesh cloth (reinforced and cracked), and scraped the wall lining three times after grinding and smoothing, the quality of the entire base will be much better at this time.

Abstract 1: Use tap water to rinse white lime.

You can rinse with tap water first, and you can use a high-pressure water gun to increase the impact when rinsing.

2. Use sulfuric acid to rinse white lime.

If it cannot be completely removed, acid cleaning is used. At this time, you can go to the hardware store to buy concentrated sulfuric acid, dilute it with some water, and then rinse. Because lime is alkaline, while sulfuric acid is acidic, it is able to neutralize it. Help remove lime.

3. If it is not a lot of lime, then use household vinegar and put it on a rag to smear it. If it is a large area, you can use a spatula.

Is it a hand of ashes with a hand of frustration?

There was no ash at all.

If the wall is relatively strong, then it will not be treated. Just brush latex paint and wallpaper. Before construction, the wall will be leveled and brushed with a layer of base film.

Plaster the wall is a common decoration method, but if you accidentally brush too much or do not paint well, it will cause some problems. Here are some solutions to the problems that arise when the walls are plastered.

1.The lime is whitish.

Lime whitening is a white stain on the wall, which is usually caused by the lime drying too quickly or too diluted. The solution is to scrape off the whitened lime state letter with a scraper or sandpaper and brush it again.

2.Lime flaking.

If the lime is peeling, you can first scrape off the loose lime with a flat tool, then sand it with sandpaper to remove the dust and debris, and finally re-brush the lime.

3.The color of the lime is uneven.

If the color is uneven when the lime is brushed, it may be caused by the primer not drying out or over-applying. At this time, clean the brush first, and then brush it again when the lime brush is dry.

4.Lime chalking.

Lime pulverization refers to the appearance of a layer of gray sand on the wall, which may be caused by the infirmity of the base layer or the excessive water on the cement floor. The lime powder needs to be scraped off and the primer repainted. If the situation is more serious, you need to redo the wall plastering.

5.The lime turns yellow.

If the lime turns yellow, it may be due to prolonged exposure to sunlight or high humidity. It can be washed with water and a mild detergent, let it dry and brush again.

In general, you need to be careful when brushing lime, pay attention to the concentration of the paint, drying time and other factors to ensure the uniformity and durability of the wall coating. If there is a problem during construction, we need to repair it in time according to the situation.

Sprinkle water on the wall, soak it through, and shovel it off.

Lime is a kind of gas plate rigid inorganic cementitious material with calcium oxide as the main component. Right lime is made of limestone, dolomite, chalk, shells, etc.

The product with high calcium carbonate content is calcined by 900 1100. Lime is the earliest cementitious material used by human beings. Lime has a wide range of applications in civil engineering, and can also be used in medicine in China. For this, antiquity.

Poems with lime as the theme have been handed down, and they have been chanted through the ages.

First of all, observe whether the lime is off or the latex paint is off, if the lime is off, then the entire lime wall needs to be removed, and then the plastering work is redone, and then a layer of primer and top coat are brushed after the lime layer is dry. Notes:

1. There are many reasons for the wall to fall dust, first of all, it may be because the internal putty layer is not treated well during the initial construction, especially when scraping the putty, if it is too thick, it will lead to potholes in the foundation layer, so a large amount of lime will fall out in the follow-up.

2. When encountering decoration construction, it is necessary to choose a more professional master, and it is best to supervise the work on site, if there are any mistakes to be corrected in a timely manner, otherwise they will suffer losses by themselves.

3. It is also very important to choose materials in the selection of materials, usually we must choose high-quality latex paint and lime powder, especially latex paint, we must choose strong waterproof, it is best not to choose inferior quality, otherwise the wall will not only be damaged, but also endanger your health.

4. If the construction is relatively intact, then it may be the ash caused by improper use of the follow-up, do not hit the wall when using the wall at ordinary times, do not scribble on the wall, and remove any stains in time if there are any stains.
